I have a question?

You are saying that light is equivalent to 0 acceleration, then in that context explain why a person traveling at some percentage below that speed
experiences time dilation (in essence accelerates temporally)?

Any thoughts?

Light is not equivalent to acceleration at all.

It does not accelerate. It is the speed it is.

Acceleration is the rate of change of velocity. In order to have a value for acceleration, you have to have a change of velocity. in vacuum, light
does not have any velocity changes. Therefore its acceleration is zero.

Considering that time itself is a man made measurement concept of linear distance, and that we have barely scratched the surface of quantum physics as
it has many applicable properties that could be applied to such (on paper), the idea while improbable is certainly possible, just not at this stage of
human understanding of the universe. Which would be needed to formulate the tech needed to produce such results.

But in respect to the development of a vessel that can travel near c there would be an acceleration to that speed.

Say for example one is looking at a rotating black hole that is fed by a Red Giant Star. In relation to energy absorbed vs. energy dissipated, what
would be the maximum rate of rotation? In such a case could a well fed supermassive black hole actually exceed a rotational speed greater than 1/2
that of light?

True, but you can't ask if something is faster than the acceleration of light, because it's like asking if something is bluer than the whichness of
what.

The maximum rate of rotation of a fictionally defined object would be reached when the outer circumference approached the speed of light.

The maximum rate of rotation of a real object is going to be limited by the mechanical properties of the object. Fast enough, and it flies to pieces.
Conversely, an infinitely rigid object (back to engineering fiction) can't rotate at all. If you had an infinitely rigid disk, you could detect the
absolute rotation of the universe.

Are you implying that a black hole could act as an edge??

If one reaches the speed of light then one reaches infinite density. Are you suggesting a large star (say one who's mass exceeds the orbit of Mars) in
an implosion achieves infinite density???

How could a photon traveling at the speed of light be influenced by a black hole if the force generated by it was not the result of infinite density?

Light has a finite speed. When your escape velocity exceeds the speed of light, light will never be able to leave. The old fashioned Newtonian
calculation for this gives you numbers that aren't all that far off as a first approximation.

Ok in context the reason a photon bends and enters a black hole, could be considered a reason to present that a photon does not actually achieve the
speed of light?

Why?

You can, in point of fact, have a singularity that's nothing but photons, according to Wheeler. Although the current energy density of the universe
probably precludes making any new ones, unless you're a type IV civilization.

Because a photon traveling at the speed of light, if it had any mass, that mass is in infinite density. So the only object that could affect it to the
degree that a black holes could be defined (hypothetically) as having a degree of density in excess of that of the photon. Further Wheeler
presentation of a singularity made of nothing but photons implies spagetification of mass to nothing but photons.

Nope. A photon has no rest mass. It has a tiny bit of relativistic mass, which will cause mbkennel to spit at me for being not quite accurate, seeing
that that doesn't hold for photons, technically. The correct answer for that one is actually in the stress-energy tensor but that, as they say, is
not within the scope of this discussion.

Well, not really, it's another stress-energy tensor thing. To get a kugelblitz, you not only have to have enough photons, you have to line them up
just right...

So what is it we are made of???

Well, at one time, I was made of snips, and snails, and puppy dog tails, but that was more than 40 years ago.

Then I went through the stage where I was all hair and meat and big stinky feet, but now I'm stardust, I'm golden, I'm billion year old carbon, and
no one can stop me now, 'cause we are all made of stars.

Sorry this is a dumb question, but exactly why do they need to do relativistic corrections for GPS? Isn't a GPS satellite in orbit moving very fast
(so its time slows down relative to observer on the ground) but it is also further away from earth's center of gravity (so time on the ground would
go slower). Wouldn't these two effects cancel out for an orbiting object? Thank you.

You ever seen blood in a tube and put into one of those spinning things? It separates the blood and stuff right or mix masters it? I would assume
that if you did this at 99.99999% at the speed of light you would make a dead human. That's it. Dead blood everywhere. Dead...
